How to Write Directly on the Brain

The video explores how the brain processes visual information and the role of the visual cortex. It discusses historical and modern research on brain stimulation, revealing how scientists can create visual perceptions without using the eyes. Early studies showed that stimulating the visual cortex could produce spots of light, known as phosphines. Recent breakthroughs have allowed researchers to trace shapes directly on the brain, offering potential for visual prosthetics. This technology could help those who have lost sight by using computer vision to navigate the world.
